A key book from a fascinating moment in the history of the science of genetics. Weismann summerises and criticises the various current theories of inheritance - Darwin, Lamarck, Nagelli. Exposition of Weismann's germ plasm theory, somatic and germ cells, drawings of the stages of cell division showing what I think would be called chromosoms today - he calls them "loops". Diagrams of how these "loops" could be modified in inheritance. The 1866 work of Mendel was unknown at this time (1892) but repeated or rediscovered by de Vries later in the 1890's.
The two volumes are in very good condition. Pages of the second volume uncut.

A complete first edition, three volume set of the classic (and brilliant) summary of all the sciences as of 1837. Mentions Faraday, Cuvier, Lyle, and hundreds of others. Darwin had just returned on the Beagle in 1837 - so Pre-Darwin. Original calf bindings, all tight. Marbled inside covers and all text block edges. Original (19th century?) owners' signature in ink on all three title pages. Otherwise unmarked throughout. Foxing on end papers only (caused by adjacent marbling?). All text blocks complete and in very good condition.
